One can approach the economics of the arts, as any field of applied economics, in either of two ways. First, one can treat economic theory and econometric technique as subjects settled by specialists in those fields, to be used in the ec onomics of the arts as they are given, very much as if one were studying the demand for maize. Alternatively, one can treat the economics of the arts as a field which may need and suggest its own developments in theory and technique, suitable to its spec ial problems and processes, from which general economic theory and econometric theory might in principle learn something. Perhaps this latter view is implausible, given the high state of development of economic theory and econometrics in the modern liter ature. Yet many of the advances embodied in these fields have come from particular areas of application-and the economics of maize has been a particularly fertile field.I am indebted to participants in the Seventh International Conference on Cultural Economics, Fort Worth, Texas, October 1992; to p articipants in the Seminar on the Economics of the Arts, Venice, Italy, December 1992; to participants in the conference of the Pennsylvania Economists' Association, Wiles-Barre, PA, June, 1993; to participants in the second conference on Simulating Soci eties, Siena, Italy, July 1993; to participants in the conference of the Society for the Advancement of Behavioral Economics, Rensselaerville, NY, August 1993; and to participants in the Third Conference on Artificial Intelligence in Economics and Manage ment, Portland, OR, August 1993, for useful comments on topics related to the research reported in this paper.

Gender differences among sagittal plane knee kinematic and ground reaction force characteristics during a rapid sprint and cut maneuver

Women are more prone to anterior cruciate ligament (ACL) injury during cutting sports than men. The purpose of this study was to examine knee kinematic and ground reaction forces (GRF) differences between genders during cutting. Male and female athletes performed cutting trials while force platform and video data were recorded (180 Hz). Differences (p < . 05) were observed between groups for knee flexion at contact and GRF at maximum knee flexion. Women averaged 5.8 degrees less flexion at contact and 1.0 N. (kg x m x s(-1))(-1) greater GRF at maximum flexion. Knee range of motion and peak GRF variables were not significantly different, but women had greater values. Women exhibited technique characteristics believed to increase ACL injury risk, but men exhibiting similar characteristics were also observed and could also be at risk.  相似文献

Maximal-intensity isometric and dynamic exercise performance after eccentric muscle actions   总被引：3，自引：2，他引：1

A well-documented observation after eccentric exercise is a reduction in maximal voluntary force. However, little is known about the ability to maintain maximal isometric force or generate and maintain dynamic peak power. These aspects of muscle function were studied in seven participants (5 males, 2 females). Knee extensor isometric strength and rate of fatigue were assessed by a sustained 60 s maximal voluntary contraction at 80 degrees and 40 degrees knee flexion, corresponding to an optimal and a shortened muscle length, respectively. Dynamic peak power and rate of fatigue were assessed during a 30 s Wingate cycle test. Plasma creatine kinase was measured from a fingertip blood sample. These variables were measured before, 1 h after and 1, 2, 3 and 7 days after 100 repetitions of the eccentric phase of the barbell squat exercise (10 sets x 10 reps at 80% concentric one-repetition maximum). Eccentric exercise resulted in elevations in creatine kinase activity above baseline (274+/-109 U x l(-1); mean +/- s(x)) after 1 h (506+/-116 U x l(-1), P < 0.05) and 1 day (808+/-117 U x l(-1), P < 0.05). Isometric strength was reduced (P < 0.05) for 7 days (35% at 1 h, 5% at day 7) and the rate of fatigue was lower (P < 0.05) for 3 days at 80 degrees and for 1 day at 40 degrees. Wingate peak power was reduced to a lesser extent (P < 0.05) than isometric strength at 1 h (13%) and, although the time course of recovery was equal, the two variables differed in their pattern of recovery. Eccentrically exercised muscle was characterized by an inability to generate high force and power, but an improved ability to maintain force and power. Such functional outcomes are consistent with the proposition that type II fibres are selectively recruited or damaged during eccentric exercise.  相似文献
